Vhile I have shown and described one preferred form of my invention, it will be understood that I do not wish to be limited thereto, since various modifications may `be made without departing from the scope of my invention, as defined in the appended claims. Y i

I claim: l. A mine car body construction comprising a heavy reenforced central bottom portion composed of a plurality of transversely spaced inverted T-shaped beams extending the entire length of the car bottom, heavy the entire length of said car and supported on the flanges of lsaid-T- shaped beams, a plurality of bails-extending undersaid central bottom portion and bent upwardlyalong the side face of said bottom portion then bent outwardly for an ap reciablel distance on a line with the top' ace of said bottom portion to .form bottom extension supports and then bent upwardly tol form body side supports, metal sheets secured to said bails to form ,sides and bottom extension portions of said body, y,and bail brackets secured to said bails at afpoint kadjacent the outer Vend of the bottom extension portions and at a point underlsa'id central bottom -port-ion to reen'force and'stifl'- en the structure. Y 1 l2. Amine car body construction comprising aheavy reenforced central bottom p01'- t-ion composed of a plurality of transversely spaced inverted T-sliaped beams extending the cntirelengtlr of the Vcar bottom, heavy planks extending the entire length vvof said car and supported on the flanges of said T- shaped eams, other short lengths of plank-V. ing secured 'to the under side of VVsaid central bottom portion at eachend to form bumper sills, a plurality of bails extending vunder said central bottom portion and bent upwardly valong the side faces of said bottom portion then bent outwardly for an appreciable distance' on a line with the top face of said bottom 4portion to form bottom extension supports and then bent upwardly to form body side supports, metal sheetssecured to said bailsto form sides and bottom extension lportions of said body,andbail brackbails at a'point adjacent the outer end of the bottom extension ysupporting portions and at-a point under saidy central bottom port-ion to reenforce and still'- en the structure. l Y j A 3.' Amine lcar body construction comprispreciable distance on a line l'outer end of the bottom car and supported on the flanges of said T- shaped beams, a plurality of bails extending under said central bottom portion and bent upwardly along the side faces of said bottom portion then bent outwardly for an apwith the top face of said bottom portion to form bottom extension supports and thenbent upwardly to form body side supports, metal sheets secured to said bails to form sides and bottom extension .'portionsof'saidfbody, bail brackets secured to said bails at a point adjacent the extension supporting portions and at a point under said central 'bottom'portion to reenforce and stiften the structure, an all-metal end rigidly secured inone end of saidvibody and an all-metal end hiigedly secured to the other end of said bo y.

4. vIna mine car body construction a reenforced central bottom portion comprising a plurality of transversely spaced inverted T- shaped beams extending the entire length of the car bottom, and heavy wooden planks extending the entire length of said car and supported on the flanges of said beams. 5. In a mine car body construction a reenforced central bottom portion comprising a plurality of transversely spaced inverted T-shaped beams extending the entire length of the car bottom, heavy planks extending the entire length of said car and supported on the flanges of `said beams, and means for securing said beams and said Vplanks together as a unit, said means including outer bail members extending transversely ofz said bottom portion, inner strap members extending parallel to .said bail members, and bolts extending through said beams, said planks, and said lbails and straps.

In testimony whereof, I have hereunto set my hand. y JOSEPH L. SHULAR.
